Abstract
1513196 Extracting xylose from xylancontaining material SUD-CHEMIE AG 4 Oct 1976 [8 Oct 1975] 41050/76 Heading C2S A process for the two-stage digestion of hemicelluloses of xylan-containing natural products to obtain xylose comprises (i) treating the starting material in a first stage at standard pressure or elevated pressure and elevated temperature with an alkali hydroxide solution in sufficient amount to split off and neutralize the acetic acid linked in the starting material, filtering off the alkaline solution from the reaction vessel, (ii) extracting the residue whilst in the same vessel at 20-120 C. with at least one liquid surge and (iii) subjecting the solid residue to an acid treatment in a second stage in the same vessel at elevated pressure and temperature, filtering off the acid solution from the reaction vessel and extracting the residue obtained with at least one liquid surge and processing the solution and extract from stage (iii) for the recovery of xylose and xylitol and optionally processing the solution and extract from the first stage for the recovery of organic acids and lignin.
